Write down the electron distribution of chlorine atom. How many electrons are there in the L shell? (Atomic number of chlorine is 17).
Answer :
Since the atomic number (Z) of chlorine is 17,
Atomic number of chlorine atom = 17
So, its electronic configuration is
K L M
2 8 7.
The electronic configuration of chlorine will be 2, 8, 7. There are eight electrons in the L shell (second shell).
